It can be clearly seen, how the current differs above the methane seeps (blue square). Simulation and visualization: GEOMAR.

Effectiveness of methane-consuming bacteria in the ocean moderated by ocean currents

Ocean Currents Impact Methane consumption Study in Nature Geoscience on interactions between marine microbiology and oceanography Offshore the Norwegian Svalbard archipelago, methane gas is seeping out of the seabed in several hundred meters depth. Luckily, bacteria are consuming a large proportion of the methane before it reaches the surface and is released to the atmosphere,…

Abiotic methane discovered under the Arctic Ocean

From CAGE – Center for Arctic Gas Hydrate, Climate and Environment New source of methane discovered in the Arctic Ocean Methane, a highly effective greenhouse gas, is usually produced by decomposition of organic material, a complex process involving bacteria and microbes. But there is another type of methane that can appear under specific circumstances: Abiotic…

Methane deceptions

Deception, agenda and folly drive latest Obama EPA anti-hydrocarbon rules. Are farmers next?   Guest essay by Paul Driessen First they came for the coal mining and power plant industry, and most people did not speak out because they didn’t rely on coal, accepted Environmental Protection Agency justifications at face value, or thought EPA’s war…

Another IPCC modeling failure – so THAT’s where the atmospheric methane went

From Oregon State University – Scientists discover carbonate rocks are unrecognized methane sink CORVALLIS, Ore. – Since the first undersea methane seep was discovered 30 years ago, scientists have meticulously analyzed and measured how microbes in the seafloor sediments consume the greenhouse gas methane as part of understanding how the Earth works. The sediment-based microbes…

The ‘methane hotspot’ identified in the Four Corners area of the U.S. Southwest can be fixed with some preventative maintenence

Study period predates the widespread use of hydraulic fracturing. | One small “hot spot” in the U.S. Southwest is responsible for producing the largest concentration of the greenhouse gas methane seen over the United States – more than triple the standard ground-based estimate — according to a new study of satellite data by scientists at…

Researchers at Brazil's National Institute for Space Research calculated that the world's largest dams emitted 104 million tons of methane annually and were responsible for 4 percent of the human contribution to climate change.

Methane – damned if you do, dammed if you don’t

Drowned tropical forests release too much methane Eric Worrall writes: A new study performed in Laos suggests that building Dams in tropical locations exacerbates climate change. According to Scientific American; “In Asia, Africa and South America, … , masses of methane are produced from dams by the drowning of tropical forests in them. As long…
